Additional Information

The reporting user(s) did not provide additional information.

Start with electrum/wallet_db.py at _convert_version_17 and trace how its stored transaction data is passed to electrum/transaction.py during wallet loading. Reproduce the upgrade failure with the reported transaction data and determine what successful wallet migration and transaction initialization should look like.
